KEITHLEY 6430 Sub-Femtoamp Remote SourceMeter

The Keithley 6430 SourceMeter combines a precise, low-noise, highly stable DC power supply with a lownoise, highly repeatable, high-impedance multimeter and a remote preamplifier for ultra-low current measurements. It has 0.012% basic accuracy with 5½-digit resolution. At 5½ digits, the SourceMeter delivers 520 readings/second over the IEEE-488 bus. At 4½ digits, it can read up to 2000 readings/second into its internal buffer. The unit has broad source and measurement ranges:
Source voltage from 5μV to 210V; measure voltage from 1μV to 211V.
Source current from 0.5fA to 105mA; measure current from 10aA to 105.5mA.
Measure resistance from 100μΩ (<100μΩ in manual ohms) to 21.1TΩ.
Maximum source power is 2.2W.

Clipping
Clipping is the limiting of a signal so that it never exceeds some threshold.

Line Regulation
Line regulation is the capability to maintain a constant output voltage level on the output channel of a power supply despite changes to the input voltage level.

Peak Envelope Power
Peak envelope power is the maximum value of the envelope power. Envelope power is measured by making the averaging time much less than 1/fm where fm is the maximum frequency component of the modulation waveform. The averaging time is therefore limited on both ends: (1) it must be small compared to the period of the highest modulation frequency, and (2) it must be large enough to be many RF cycles long.

RMS
RMS or root mean square is a statistical measure of the magnitude of a varying quantity
